To all whom it may concern: 2 her 6 provided at its upper side with an Be it known that l', BASIL lP. Bassoon, extension which is secured by bolts or other 55 a citizen of the United States, residing at fastening devices 7 tothe underside of tank Chicago, in the county of Cook and State of '5. In said extension of chamber .6 is Illinois, have invented new and useful lmformed a passage 8 which leads from the provements in Measuring Devices for Cantank 5 to the interior of said chamber 6, Filling Machines, of which. the following is the inner or lower end of said passage con- 60 a full, clear, concise, and exact description, stituting an inlet port for said chamber. reference being had to the accompanying At the underside of said chamber is prodrawing, forming a part of this specifivided an outlet port 9 through which the cation. i j material is discharged from said chamber ,My invention relates to improvements in and into the cans which, in the operation of 65 measuring devices for can filling machines, the machine, are arranged below-the measand has for its object the production of a uring devices. 5 device of this character which will permit Rotatably mounted within the chamber 6 I of ready and expeditious cleaning of the for the control of the inlet and outlet ports same so as to permit ofthe machine being thereof is a tubular valve 10 formed with an 70 readily maintained in a sanitary condition, opening 11 adapted, upon rotation of said A further object is the production of valve, to alternately register with the inlet mechanism, of the character mentioned and outlet ports of the chamber-to alterwhich will be of durable and economical nately effect inlet to and discharge from construction and eflicient in use. said chamber.

Other objects will appear hereinafter. Theopposite ends of chamber 6 are open, With these objects in view, the invention the valve 10 projecting through one of said consists generally in a novel construction open ends of said chamber, and being prowhich permits of ready assembling and disvided with an annular ear 12 through the assembling whereby access to the various inmedium of which sai valve is rotated. so ternal parts of the mechanism is facilitated. Said gear is held in co-operative or fixed The invention will be best understood by relation with the chamber 6 by means of a reference to the accompanying drawings plurality of an lar holders 13 placed around said cham er and secured thereto by' wherein- 1 Fig. 1 is a partially sectional side eleva- ,screws 14:. lhe members 13 engage an an- 85 tion of a measuring device for can filling nular flange 15 formed upon the gear 12, as machines embodyin the invention, adjacent clearly seen in Fig. 2.

use in connection with a can filling machine The arrangement is such that in the operprovided with a tank-or reservoir 5 which ation of the machine, at which time the valve ice is adapted to contain the material to .be 10 is rotated by the gear 12, the direction filled into the cans. ,of rotation will be such that the pins 16 will The measuring device constituting the remain in engagement with the slots 1'7.

subject matter of this application is mounted Release of said valve 10 may, however, be i upon the underside of the tank 5, said measeffected, if desired,'by 'reversely rotating the uring device comprising a cylindrical chamvalve and moving the same longitudinally,

such movement of said valve causin theslots .17 to disengage the pins 16, as wlll be readily understood.

Rotation of the gear 12, as just mentioned, is effected by means of a stationary gear 18 'ineshing therewith, the arrangement being such that as the measuring dev ces revolve' with the tank 5, thegear 12 Wlll ride about and be in mesh with the, gear Mounted for axial movement wlthm the valve. is a plunger 19, the rod or stem 20 gages with a cam 24 whereby, in the .opera tion of the machine, the lunger 19 will be caused to reciprocate in t e valve 10 as the measuring device revolves. The rotation of said valve and the reciprocation of said plunger are so timed that movement of the plunger to the left, as seen in Fig. 1, will occur when the opening 11 of the valve 10 is in registration with the inlet port of chamber 6, whereas movement of said plunger inthe opposite direction will take place when said opening 11 is in registration with the outlet port 9 of said chamber, said plunger being adapted to' insure, the forcing of the material from the measuring device in the latter instance. 7

By reason of the sectional construction of the plunger rod 20, that is, the detachable connection between said rod and the section- 21 thereof, when it is desired to remove the plunger 19, the connecting device 22 needs only to be removed. whereupon the rod 20 will be disconnected from the section 21, permitting of the plunger to be removed through the outer end of the measuring chamber.

Said outer end of said measuring chamber is closed by a removable closure 25 which is.

Y in bayonet joint connection with the come spending end ofsaid chamber, said closure being provided at its periphery with a plurality of spaced outwardly projecting pins 26 which loosely engages angular slots 27 formed in said end of said chamber, as clearly seen in Figs. 1 and 2. The arrange-' ment is such, as will be seen, that connection and disconnection of said closure mayv be effected by rotating and longitudinally moving the same, as will be readily understood. When said closure is in closing position, the same seats against a shoulder 28 to form a tight connection with the end of the measuring chamber. Diametric lugs 29 are formed 1n the countersunk outer side of ,said closure which permlt 'of engagement by a suitable tool in applying or removing said closure.

1th the construction set forth, it will -beseen that an arran ement is provided which permits of ready isconne ction or disassembling of the parts. In doing this, the closure 15 is first removed. This having been done, the plunger 19 may be removed by simply wit drawing the in 22, thus disconnecting the plunger rod rom the section 21, which carries the cam roller 23. Upon removal of said plunger, the valve 10 may be readily removed by simply reversely rotating the same to effect disengagement from the pins 16 on gear 12. It will thus be seen that the various internal parts of the measuring device may be readily and quickly re moved to permit of thorough cleansing of the same, and when these parts are removed, the interior of the measuring chamber as well as the inlet and outlet ports or passages thereof are rendered readily accessible so as to permit of easy cleansing thereof. Thus with this arrangement a machine is provided which may be readily maintained in a clean and sanitary condition which is, of course, of prime importance in canning machinery. Reassembling of the parts may, of course, be as readily effected as disassembling of the same above described.

The mounting of gear 12 is such that upon detachment of valve 10 therefrom and re moval of the latter, said gear will be maintained in fixed or cooperative relation with the chamber 6 through the medium of the holders 13, so that upon reinsertion of said valve, said gear will be in proper position to receive said valve.
